Research on managing open data requires an appropriate collection of such datasets in order to test novel algorithms and techniques. Gaining insights about their properties can also inform the process of designing algorithms or benchmarks. Currently, the interface of most open data portals is limited in that regard.

Here we provide a visualization that uses Multidimensional Scaling (MDS) to depict datasets from https://www.data.gov/ . We focus on four structural (metadata) attributes of the datasets:

We also show (on the right) the distribution of these 4 attributes for each selection of datasets.
